VFD - AN OVERVIEW

Allow us to assume the travel is working on a 480V electric power technique. The 480V score is “rms” or root-imply-squared. The peaks over a 480V process are 679V. As you can see, the VFD dc bus provides a dc voltage with the AC ripple. The voltage runs concerning about 580V and 680V.The ability through the DC bus is thereafter fed to an invert
